The Matter of Time -- A General and Efficient System for Precise Sensor Synchronization in Robotic Computing
This addresses synchronization challenges for robotic applications like autonomous driving, but appears incremental as it builds on existing systems.
The paper tackles the time synchronization problem in robotic computing by presenting a general hardware synchronization system that achieves high accuracy with low energy and resource consumption.
Time synchronization is a critical task in robotic computing such as autonomous driving. In the past few years, as we developed advanced robotic applications, our synchronization system has evolved as well. In this paper, we first introduce the time synchronization problem and explain the challenges of time synchronization, especially in robotic workloads. Summarizing these challenges, we then present a general hardware synchronization system for robotic computing, which delivers high synchronization accuracy while maintaining low energy and resource consumption. The proposed hardware synchronization system is a key building block in our future robotic products.
